WELT-GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 231,465, dated August 24, 1880.

Application filed April 1, 1880. (No model.)

To. all whom it may concern Be it known that I, T. B. YOUNG, a citizen of the United States, residing at Calhoun, in the county of McLean and State of Kentucky,

have invented certain new and useful Improvements in Welt-Guides for Sewing-Machines; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and'to letters or figures of reference marked thereon, which ibrrn a part of this specification.

1 My invention relates to improvements in welt-guides for sewing-machines; and the object of my improvement is to furnish a guide for directing a welt between the parts of leather and other substances that are to be stitched together in making boots, shoes, and other articles which require the use of such a device. I attain this object by means of the device illustrated in the accompanying drawings, in which- Figure l is a plan view of my improved device, showing a clamp and screw for securing it to the table or bed of a sewing-machine, a

frame for holding the parts in position, an adjustable welt-guide, screws for holding it in position, a roller against which the edge of the leather or other substance is held While being sewed, and a piece of such material. Fig. 2

is a perspective View of the frame and guide, showing also the means forproperly adjusting 3 5 the leather. Fig. 3 is a perspective View of a sliding holder for the weltguide, by which the position of the welt between the parts in which it is placed can be controlled; and Fig. 4 is a perspective view of two pieces of material and of a welt placed between them, they being shownas stitched together.

Similar letters refer to similar parts throughout the several views.

In constructing devices of this character I use a frame,'A, of metal or of any other suitable material, and of the form shown or of any other that will admit of its being attached to the table of a sewing-machine, it being provided with a clamp, A, and screw A for mak- 5o ing the attachment.

To one of the bars of the frame A there are affixed guides or flanges B B, in or between which there is fixed a slide, B which, when properly adjusted, may be held in its position by a set-screw, B

The office of the slide B is to regulate and control the distance of that portion of the welt-guide through which the welt passes from the roller against which the edge of the material to be sewed is kept, as will be more fully explained hereinafter.

The slide B has upon its upper surface a projection, B, which is provided with a setscrew, B and an aperture, B", through which passes a rod, 0, to the outer end of which there are affixed or made a part thereof two (more or less) welt-guides, O and G The arrangement of these parts, being substantially as shown, is such that the welt guide or guides may be fixed at a greater or less distance from aroller against which the edge of the leather is kept while being sewed by adjusting the rod 0 in the projection B of the slide B and securing it in position by the set-screw B said slide being held in its adjusted position by the setscrew B The roller above alluded to is designated by the letter D, and is carried by aslide, l), which is placed between flanges D and D which are secured to the frame A, its object being to enable the operator to cause the stitches to be taken at a greater or less distance from the edge of the leather or other substance which is being operated upon, which object is attained by moving the roller D outward or inward, and at the same time changing the position of the welt-guide to correspond therewith, the frame A being at such times properly adjusted upon the table with reference to the needle or needles of the machine and to its feeding appara- 9o ratus.

In practice the two parts of the leather or other substance to be united will be passed over the surfaces of the bent portions of guides G and O one part passing over their upper 5 surfaces and the other passing underneath them, while the welt to be interposed passes between said berit or looped portions, their edges being kept in contact with the roller D while they are being passed to the needle or needles to be stitched.

I am aware that prior to my invention guides :0 adjustable guide-roller I), and the frame A,

the parts being constructed and arranged for joint operation substantially as shown and described.

In testimony whereof I atfix my signature in presence of two witnesses.
